These guys are the best, they called me to let me know that they had just finished asse.bly and testing and were packaging and shipping that day, best customer service I have ever had and a quality good looking product.

I've purchased 2 of these uppers from mas, I was super impressed with the attention to detail and quality. If you want a battle rifle set up this is a excellent start. Also grab a stoner 5.3oz 308 buffer with it, the combination is absolutely insane.
Great experience
